Answer:
Na (sodium)
Explanation:
An atom, which is the smallest indivisible particle of an element, contains three sub-atomic particles namely: proton, electron, and neutron. An atom is said to be neutrally charged if it contains a charge 0.
In a neutral atom, the number of electrons and the number of protons in an element are equal. These numbers are called the ATOMIC NUMBER. That is, in a neutral atom;
proton no. = electron no. = Atomic no.
Hence, in this case where Silicon atom has an electron number of 14. If three of this electrons are removed, there will be 11 electrons left, hence, this atom becomes SODIUM element, which has 11 electrons in its atom, with chemical symbol Na.
Answer:
BaCl2+H2SO4 -----> BaSO4+ 2HCl
You need the unit of g however you must convert to moles before you can use the mole ratio to find the moles of iron, you used the molar mass of iron to find the grams of iron. since F e 2 o 3
Answer:
<h2>YES</h2>
Explanation:
Coyotes and oak trees are multicellular organisms and multicellular organisms reproduce asexually and sexually.
Many multicellular lower plants give off asexual spores, either aerial or motile and aquatic (zoospores), which may be uninucleate or multinucleate.
Answer: P = 7.1 atm
Explanation: For this problem we will use Combined Gas Law to solve for the new pressure. But never forget to convert the unit of temperature to Kelvin.
P1V1 /T1 = P2V2/ T2, Derive for P2.
P2 = P1V1T2 / T1V2
= 1.00 atm ( 3.00 L ) ( 323 K) / 273 K ( 0.50 L )
= 7.1 atm
Cancel out the units of L and K and the unit remains is in atm.
